The following excellent essay is by our current volunteer resident, Grace Jirik, who is currently nearing completion of a Bachelor of Ag Science & International Development. Grace has precisely captured why so many young people are turning hopefully to agroecological farming at the same time that others are running from industrial agriculture. With emerging young farmers like Grace lined up to take over the reins, I reckon the future looks bright!

Approximately one third of total greenhouse gases are attributed to agriculture and the food systems that support it.[1] It is predicted by climate scientists that warming of more than two degrees celsius will cause irreversible damage to the environment and catastrophic consequences for humanity.[2] Thus, it is of vital importance that the sector drastically shifts away from further industrialisation and instead adopts methods to reduce the contribution to the climate change crisis. The population is expected to reach 8.9 billion by 2050 and increase the demand for food, particularly in the world’s poorest countries.[3] However, the calls to drastically increase food production to meet demand with further industrialisation of the sector and deforestation of arable land is an unsustainable trajectory. In reality, food systems may only need to increase production by 25% to meet demand [4] which can largely be achieved by adopting agroecological models of farming. Without a drastic remodelling of world agricultural systems, the increase in food production will have catastrophic environmental consequences and further reduce the agricultural systems capacity to produce enough food.

The emergence of the so-called “Green Revolution” and the proliferation of industrial farming in the 1960s [5] greatly increased agricultural production through the introduction of artificial fertiliser and the breeding of cultivars to respond to these inputs.[6] But after 50 years, the sector is now faced with the reality that these farming methods are unsustainable and have resulted in a drastic loss of productivity in recent decades.[7] Despite this, industrial agriculture continues to hold a powerful position due to the vicious cycle that it has forged in the sector, paired with the continued availability of cheap fuel.[8] In order to change this trajectory, farming systems need to transition to agroecological models; that is, farming that strives to “mimic natural processes, thus creating beneficial biological interactions and synergies among the components of the agroecosystem”.[9] This model must be widely adopted to help curb global warming and maintain sustainable food systems that can feed the world into the future. In the words of Fuhrer and Gregory, “There is no doubt that agriculture can (and must) be part of the solution to the problem of global warming.”[10]

Agroecological farming systems can mitigate much of the greenhouse gas emissions currently produced by agriculture. Currently, 10-12 percent of global emissions are directly from agriculture [11] and a further 4-13 percent from land clearing for agricultural land use.[12] Much of these emissions come from industrial farming methods that require high inputs of fertiliser, energy and water.[13] In contrast, agroecological farming models use more holistic land management methods. For example, the use of integrated pest management uses beneficial insects, plant deterrents, and staggered crop planting to control pests instead of heavy applications of chemical pesticide.[14] Studies have shown that on farms where integrated pest management was adopted, there was a 71 percent decrease in pesticide use and a yield increase of 42 percent.[15] If such methods were embraced across the world, the energy required for manufacture and transport of pesticide would be enormously reduced and those emissions successfully mitigated.

Similarly, the overuse of fertiliser is a significant area for mitigation potential. The greenhouse gas emissions released in fertiliser manufacture and transport represent the majority of total emissions released in agricultural ‘preproduction’.[16] In addition, direct application of nitrogen fertiliser on soil is the source of most (58%) [17] of total global nitrous oxide production; a gas that has 310 times the global warming potential of carbon dioxide.[18] By employing the use of green manures, crop rotation and regenerative methods of farming, the use of fertiliser can be cut down without sacrificing yield [19] and consequently mitigate a significant portion of the agricultural sector’s emissions.

Another area with arguably the most significant potential for greenhouse gas mitigation is carbon sequestration in soil. The Intergovernmental Panel on Climate Change (IPCC) estimates that 89 percent of agricultural carbon could be mitigated using better practices to ensure soil carbon storage.[20] Soils that contain more organic matter have a much greater ability to store carbon in the long term.[21] Due to the regenerative nature of agroecological practices such as not tilling the land, crop rotation and low stocking density, the soil on these farms tends to have far higher rates of ‘soil organic carbon’ than industrial farms [22], hence releasing less carbon into the atmosphere directly from the soil. And finally, the role of plants in metabolising carbon in the atmosphere is known, the IPCC estimates that “1,146 GtC is stored within the 4.17 b ha of tropical, temperate, and boreal forest areas”.[23] Agroforestry, the planting of trees on farmland, is a key part of agroecological farms and can be a part of the solution to widespread land clearing.[24]

In addition to mitigation, agroecological farming systems will be important in the adaptation required in the face of climate change. There are a plethora of studies that show that agroecological systems are more resilient to climatic shocks than conventional systems.[25,26] This is mainly due to the increased ground cover, higher levels of organic matter within soils and the diversified species on farm that are common in agroecological systems.[27] With the expected increase in damaging climatic events such as cyclones, floods and droughts[28], it is vital for farmers to be able to protect themselves from these events. For example, when ‘Hurricane Mitch’ hit Nicaragua in 1998, those farmers who had adopted agroecological methods such as agroforestry, had 69 percent less gully erosion and retained 40 percent more topsoil than those who had not.[29] Agroforestry is also extremely beneficial in providing shade and preventing heat stress in livestock.[30] It is also known that agroecological farms require less water[31] which will become increasingly important as temperatures start to rise and droughts become more prevalent.

Further to the physical environmental benefits, agroecological systems also build community and individual adaptive capacity. The IPCC has recognised that people who are “socially, economically, culturally, politically, institutionally, or otherwise marginalised are especially vulnerable to climate change”.[32] Thus, for the majority of the world’s poor living in rural areas and working in agriculture[33], the challenges of global warming will be especially debilitating. Many efforts in the past that attempted to improve the livelihood of these farmers simply replicated the industrial farming model of increasing inputs in order to raise yields of a globally marketable cash crop.[34] However, the failures of this method are evident, as “815 million hungry people are family farmers who produce most of the planet’s food”.[35] Agroecological farming systems can help protect from shocks in climate and in the market that would otherwise undermine these livelihoods. By diversifying what is farmed instead of producing a monocultural cash crop, the farmer is less at risk of climate related plant defects or market failure of that particular product.[36] Additionally, an agroecological model that is less reliant on external inputs such as fertilisers, chemicals and diesel fuel makes farmers less dependent on a potentially vulnerable supply chain.[37] Agroecology has also been shown to bring a strong social dimension to farming in strengthen the social security networks that are essential to resilience.[38] This is especially true when agroecological methods of farming has been disseminated from farmer to farmer through self organisation, collective action and reciprocity.[39]

To conclude, agroecological farming can be a powerful tool in reducing the agricultural sector’s greenhouse gas emissions. The methods can successfully mitigate the majority of emissions currently released. Agroecology will also be vital in societal adaptation to the effects of climate change. It will also strengthen adaptive capacity for individuals and communities. Agroecology has the power to divorce agriculture from the industrialisation that causes global warming.

Emotional Dimension

My emotional reactions to this topic were strong because much of my life outside of university revolves around this exact issue; how can I fix farming? Half of my degree is agricultural science and in a matter of months I will be on my journey to be a farmer, outside the walls of La Trobe. Researching this topic was exciting because I was able to find actual data and evidence that showed the way I want to farm is actually the best model for the planet and for my own profit.It was encouraging and enlightening information that I will take with me on my future farming ventures.

However, researching was also incredibly frustrating at times. To be faced with the evidence that agroecological farming could be the answer to curtailing the agricultural sector’s contribution to global warming, but no evidence of wide adoption is infuriating as well as confusing. The models that are in place at the moment are undermining farmers by locking them into a heavy reliance on fossil fuels and putting money into the pockets of middle men.[40]

Recently I have had my eyes opened to the food sovereignty movement, mainly as a consequence of being an intern for Tammi Jonas, the current president of the Australian Food Sovereignty Alliance. Food Sovereignty “asserts the right of peoples to nourishing and culturally-appropriate food produced in ethical and ecologically-sound ways, and their right to collectively determine their own food and agriculture systems”[41]. With my new knowledge of the movement and its importance around the world, researching how ‘big agriculture’ is dismantling farmers’ and consumers’ right to food sovereignty, was particularly emotional.

At times throughout the research I also felt helpless. Many of the industrial systems have been implemented around the world to create a dependency on the model through regulations, retail imperatives and policies that keep fossil fuels cheap.[42] This is why many farmers are ‘locked in’ to an industrial model despite how they may feel about the environmental damage they’re causing. Although I believe that there is huge opportunity for change, researching the vicious cycle of industrial farming that so many people are caught in made me feel somewhat helpless.

Existential Dimension

Much of the research on the topic confirmed my place in the world. Throughout my degree I have been exposed mainly to industrial practices of farming; however, through my own exploration I had found the agroecological alternative. I feel like I belong firmly within this space and am excited for my future in farming and being apart of the uptake of agroecology.

Additionally, I feel more encouraged to be involved in the push against industrial farming. Before researching the topic, I felt comfortable in my future of being an outlier in agriculture with alternative methods. Now I feel strongly about being a part of a global movement away from intensive farming and spreading the information that farmland will be more productive if the agroecological methods are adopted. The research showed that there are members of the industry that rely on this information not becoming wide knowledge due to their reliance on exploiting farmers. These members include fossil fuel companies, fertiliser and pesticide manufacturers and GMO companies who breed specific products to flourish in intensive environments.

However, throughout the research I found that ‘scaling up’ was a popular topic.[43] Arms of the UN such as the Human Rights Council and the Food and Agriculture Organisation of the United Nations (FAO) are particularly interested in how we can scale up production via agroecology.[44] This made me question my position on the issue. Although we do need to adopt better farming methods to feed the future population, one of the most significant barriers to greenhouse gas mitigation is growth.

The capitalist ideal of constant growth goes hand-in-hand with environmental degradation. And, as Herman Daly puts it; “the term ‘sustainable growth’ when applied to the economy, is a bad oxymoron – self-contradictory as prose, and unevocative as poetry”.[45] An issue that is too big to address in this essay, but unavoidable when talking of this topic, is the fact that as the population and economies continue to grow, so will greenhouse gas emissions. Agroecological agriculture will certainly bring a better environmental future, but the pressure of population is difficult to limit.

Empowerment and Action Dimension

Researching alternative methods of farming has definitely fostered a sense of responsibility to be ecologically conscious in my future farming ventures. I already knew that I wanted to run a ‘sustainable’ farm, but now I feel as if I have a better sense of direction and can better picture what form it might take.

I am at a point in my life where I believe I have the privilege to farm how I like and think that I would have enough engaged and environmentally conscious customers to be able to prosper. However, I haven’t even made it to the planning stage of my future career and I imagine that eventually I will come up against barriers and be moved to protest. For example, in Australia there has been numerous cases of overregulation of small scale farms due to the lack of differentiation between intensive and agroecological models.[46]

Though I admit that I may not be the most “engaged actor” in the near future, I believe that as I establish myself as a farmer I will become more engaged as time progresses. I will be directly exposed to the difficulties faced by small scale farmers and feel a stronger sense of responsibility to stand up for our rights. Through researching this topic and other extracurricular exploration, I have discovered peasant movements and groups small scale farmers doing exactly this and I already feel a sense of belonging among them. This subject has helped me immensely by further opening my eyes to the reality of fossil fuel domination of our society and the need to dismantle their power structures.
